fs: ext4: check the minimal partition size to mount
No need to mount a too small partition to handle a EXT4 file system. This patch add a test on partition size before to read the SUPERBLOCK_SIZE buffer and avoid error latter in fs_devread() function. Signed-off-by: Patrick Delaunay <patrick.delaunay@foss.st.com>
